Multiple news outlets reported Monday night that new Metro-North President Joseph Giulietti has submitted a preliminary 100-day improvement plan to state department of Transportation Commissioner James Redeker.

According to WTNH-TV, in submitting the plan, Giulietti wrote, "This plan requires returning to the basics of good railroading. First and foremost, however, we must rebuild a culture of safety at Metro-North to serve as the railroad's unshakable foundation."

Giulietti's letter reportedly laid out three external reviews that he said are underway and "will inform our efforts.

The second measure, according to WTNH's account of Giulietti's letter, would be a "deep-dive" review of Metro-North's safety, operations and training, to be conducted by the Federal Railroad Administration.

The third review, according to the report, would be the ongoing investigations of the National Transportation Safety Board into a number of incidents in 2013, a year that included a derailment and collision in Bridgeport that injured 76 people and another derailment in the Bronx, N.Y., in which four people were killed.
